Ewelina Chrzanowska started as a CSM at Codewise, led a team of 16 across EMEA at Splunk, and now manages three teams (support, tech support, CSMs) at Edrone while training Polish CS managers through CS for Poland School.In this conversation, we break down:→ The biggest misconception about customer success (hint: it's not just tech support or sales catch-all)→ How to build a CS team from zero (and why hiring right is more important than perfect processes)→ The one trait every great CSM needs (open-mindedness and handling hard situations)→ When to implement customer success at your company (before churn alerts become a crisis)→ Do QBRs actually work? (Only if you do them right)→ How she improved renewal rates by 10% in one year (the exact process)→ Managing CS across EMEA: different languages, cultures, and customer needs→ Why metrics aren't everything (and the worst advice in CS)→ Should CSMs handle renewals and expansions or just retention?→ Will customer success exist in 15 years or get absorbed back into sales?→ How AI/LLMs are actually helping CS teams (not replacing them)Ewelina went from studying tourism and leisure to building customer success teams at fast-growing startups and global enterprises. She's managed teams from 16 people across EMEA to now leading three different functions (support, tech support, CSMs) at Edrone.If you're a founder trying to reduce churn, a CS leader building a team, or a CSM trying to level up, this conversation is packed with tactical insights from someone who's built CS functions multiple times at different scales.
